Ch 4: GED Science - Chemical Reactions, Acids, and Bases: Help and Review

About This Chapter

The Chemical Reactions, Acids and Bases chapter of this GED Science Help and Review course is the simplest way to learn about chemical reactions, acids and bases. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of chemical reactions, acids and bases.

Who's it for?

Anyone who needs help learning or mastering GED science material will benefit from taking this course. There is no faster or easier way to learn GED science. Among those who would benefit are:

  • Students who have fallen behind in understanding types of chemical reactions or measurements of acids and bases
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about chemical reactions, acids and bases
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the chemical reactions, acids and bases chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the chemical reactions, acids and bases chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any chemical reactions, acids or bases question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a chemical reactions, acids and bases unit of a standard GED science course. Topics covered include:

  • Water properties
  • Components of solutions, including solutes and solvents
  • Osmosis, diffusion and saturation processes
  • Measurements of acids and bases on a pH scale
  • Methods for writing and balancing chemical reactions
  • Redox reactions and common chemical reactions

15 Lessons in Chapter 4: GED Science - Chemical Reactions, Acids, and Bases: Help and Review
Properties of Water

1. Properties of Water

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Solutions, Solutes, and Solvents

2. Solutions, Solutes, and Solvents

Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.

Osmosis, Diffusion and Saturation

3. Osmosis, Diffusion and Saturation

The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.

Acids and Bases

4. Acids and Bases

Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.

Basic Properties of Chemical Reactions

5. Basic Properties of Chemical Reactions

Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.

Common Chemical Reactions and Energy Change

6. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

7. Redox (Oxidation-Reduction) Reactions: Definitions and Examples

This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.

Acidic Solutions: Properties & Examples

8. Acidic Solutions: Properties & Examples

Acidic solutions are found everywhere in the natural world and are an important part of our everyday lives. This lesson defines acidic solutions and discusses their fundamental properties. Several examples of acidic solutions from the natural world and industry are also provided.

Arrhenius Acid: Definition & Examples

9. Arrhenius Acid: Definition & Examples

A scientist named Svante Arrhenius defined an acid as a compound that increases the proton (H+) concentration in a solution. This definition of an acid is what we now call an Arrhenius acid, which is the main focus of this lesson.

Buffer System in Chemistry: Definition & Overview

10. Buffer System in Chemistry: Definition & Overview

In many ways, our lives are dependent on functioning buffer systems. Learn the definition of a buffer system, understand how it works and assess your knowledge with a quiz.

Chemical Reaction Catalyst: Rates & Overview

11. Chemical Reaction Catalyst: Rates & Overview

Catalysts are common in both industrial processes and in the human body. This lesson will explain how they work and why we need them. A quiz will test our knowledge.

Closed System in Chemistry: Definition & Example

12. Closed System in Chemistry: Definition & Example

This lesson provides a basic definition of a closed system from thermodynamics. Examples are included to provide students with illustrations of closed systems that are encountered within chemistry.

Combination Reaction: Definition & Examples

13. Combination Reaction: Definition & Examples

There many types of chemical reactions. In a combination reaction, you can predict the product if you know what goes into it. Find out more about combination reactions and see some examples.

What is Sodium Bicarbonate? - Structure, Formula & Uses

14. What is Sodium Bicarbonate? - Structure, Formula & Uses

Have you experienced heartburn? Do you like cooking and baking? Have you encountered stubborn stains? If you answered yes to any of these, then sodium bicarbonate is your friend. In this lesson, we will discuss sodium bicarbonate and its many uses.

What Does Chemical Mean in Science?

15. What Does Chemical Mean in Science?

In this lesson we will learn what a chemical is, how it is defined in science, and the importance of chemicals to our life. We will also learn how society views chemicals versus the definition in science.
